Sprayer

Abstract

A sprayer includes a sprayer casing, a power module and a spray nozzle. The sprayer casing is configured to contain a liquid. The power module is connected to the sprayer casing and is configured to energize the liquid in the sprayer casing, so that the liquid carries a first charge. The spray nozzle is connected to the sprayer casing and is configured to atomize the liquid with the first charge and spray it onto the external object with the second charge. The first charge and the second charge are opposite. The sprayer of the present invention has an excellent atomization effect and an improved the utilization rate of the atomized liquid.

What is claimed is: 
     
       1. A sprayer, comprising:
 a sprayer casing, comprising a cavity for containing a liquid; 
 a power module, connected to the sprayer casing and configured to energize the liquid in the cavity to make the liquid carry a first charge; 
 a blower; 
 a spray nozzle, connected to the sprayer casing and configured to atomize the liquid with the first charge and spray it onto an external object with a second charge, wherein the first charge and the second charge are opposite; and 
 a vent pipe; 
 wherein the blower is provided between the cavity and the spray nozzle; the spray nozzle comprises a spray nozzle casing, a transmission part and a spray component; 
 the spray nozzle casing is connected to the blower; and the blower is configured to provide a force to allow the spray component to rotate, so that the spray component is rotatable with respect to the transmission part to form a vacuum inside the spray component; and 
 one end of the vent pipe is connected to the blower, and an other end of the vent pipe extends into the sprayer casing; and the vent pipe is configured to introduce a wind generated by the blower into the cavity of the sprayer casing to obtain a pressure in the cavity. 
 
     
     
       2. The sprayer of  claim 1 , wherein one end of the blower is connected to the sprayer casing, and the other end of the blower is connected to the spray nozzle; and the blower is configured to provide the spray nozzle with a force that allows the atomized liquid with the first charge in the cavity to be sprayed onto the external object with the second charge. 
     
     
       3. The sprayer of  claim 2 , further comprising a connection part; wherein one end of the connection part is connected to the sprayer casing, and the other end of the connection part is connected to the blower. 
     
     
       4. The sprayer of  claim 3 , further comprising a handle; wherein the handle is connected to the connection part, and the handle is rotatable with respect to the connection part. 
     
     
       5. The sprayer of  claim 2 , wherein the transmission part and the spray component are both arranged in the spray nozzle casing; the transmission part is connected to the spray component and the spray nozzle casing, respectively. 
     
     
       6. The sprayer of  claim 5 , wherein the spray component comprises a blade component and an outlet; the outlet is connected to the blade component and has an opening; and the transmission part passes through the blade component and extends into the outlet; and the blower is configured to provide a force to allow the blade component to rotate, and the blade component drives the outlet to rotate with respect to the transmission part to form a vacuum inside the outlet. 
     
     
       7. The sprayer of  claim 6 , wherein the outlet is flared towards an end of the outlet away from the blade component. 
     
     
       8. The sprayer of  claim 6 , wherein the blade component comprises a fan blade and a connecting pipe; the fan blade and the outlet are arranged on the connecting pipe, and the transmission part is inserted in one end of the connecting pipe; and the fan blade is rotatable with respect to the transmission part, so as to drive the outlet to rotate synchronously through the connecting pipe. 
     
     
       9. The sprayer of  claim 1 , further comprising an electrode assembly, wherein the electrode assembly extends into the cavity to allow the electrode assembly to contact with the liquid; and the electrode assembly is electrically connected to the power module. 
     
     
       10. The sprayer of  claim 1 , further comprising an energy supply part which is electrically connected to the power module and is configured to provide electrical energy to the power module.
